Knoppix (Debian) pppoeconf and cable modem
When i try to use pppoeconf to configure my cable modem I get a message saying that my another program is using my modem already???
I am with Cable Wanadoo in the Netherlands. My modem is a COM 21.
I also have a dual boot system using Windoze. The modem functions ok in windows.
Any Ideas???
Further info:
I recently installed Windows and reconfigured the network. I heard a rumour that Windows leaves the Modem turned on even when you are not connected to the internet. I think that it may be the source of the pppoe service operating error message. i have a dual boot system. I'm still not brave enough to try Linux only! Soon I hope!
This info is from the Cable Modem How-To:
The current Wanadoo cable modems operate via the serial port, acting like normal modems, answering AT commands like phone modems. The setup is really very easy, because all the chat script needs to do is dial ATDT4. (this is in ppp-on-dialer). Hence it uses PPP, which is unusual for most cable modems.
Relevant files are included /etc/ppp/ppp-on
DIALER_SCRIPT=/etc/ppp/ppp-on-dialer
exec /usr/sbin/pppd -detach /dev/ttyS0 115200 connect $DIALER_SCRIPT &
/etc/ppp/ppp-on-dialer
exec /usr/sbin/chat -e '' AT '' ATDT4
/etc/ppp/ppp-off

I've documented some things in the files themselves. The ppp-on script is called during boot time from /etc/rc.d/init.d/ppp and the ppp-off script during shutdown. The ppp-on-dialer is called from the ppp-on script. The keepalive script for keeping the connection alive as long as the computer is on (might as well, right?) is called from crontab (see the keepalive file for details). The /etc/sysconfig/network file specifies the default gateway for routing. The resolv.conf tells the computer which IP of casema.net to send DNS queries to (this is pretty standard across all unixes, I believe).
I've forgotten to include the /etc/ppp/pap-secrets which should be the same as the ExpressNet, Maryland, Maryland. There's also the question of the ip-up, ip-down. These however, didn't need to be changed. I've also included the options.ttyS0 file, which should be in /etc/ppp/ppp-on. It is read by the pppd daemon as it logs on. There are a couple options like defaultrouteadd that should be on. ttyS0 is the port where you install your modem mine is on COM1 == ttyS0. Change accordingly.

Incidentally Wanadoo recomends Roaring Penguins pppoe program.
Thanks.
Nearly there. Online at least.
Problem solved partially. I am now on the net using knoppix but I must do the following:
#su
#password
#mii-tools
reply is :
eth0: 100mbit half-duplex no-link
so then I
mii-tool -F 10baseT-HD eth0
pppoeconf as normal.
eth0 is configured static similar to my win98 setup in winipcfg but with nothing in default gateway.
My problem now is I have to be in su mode to log on. How do I change the pppoe permission so that all users can log on?
And is there a way to keep the eth0 in 10 half-duplex all the time? So I don't (or more importantly my girlfreind) doesn't have to keep typing these commands?
